SPECIFICATION forming part of Letters Patent No. 634,554, dated October10, 1899.

Application filed May 23, 1899. Serial No. 717,912. (No model.)

will enable others skilled in the art to which it,

appertains to make and use the same, reference being had totheaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

This invention has reference to improvements in dry-docks; and theinvention has for its principal object to provide a novel cons tructionof dock into the inclosure of which water can bereadily admitted .forthe floating of a ship therein and from which the water can be removedby its own gravity to permit the ships bottom and sides to be cleanedand repaired. v

A further object of this invention is to provide a simple means forallowing the water to pass from the basin or ir'iclosure in which theship is floated into a second basin or inolosure built directly upon theland and preferably surrounded by piling or cribbing to permit the Waterto soak into the ground.

Another object of this invention is toprovide a novel construction ofgates and means for opening and closing the same and also a novelconstruction and arrangement'of keelsupports and chocks and in generalto provide a dock in which the pressure upon the ships bottom and thesides can be regulated and maintained the same throughout the entiresurface of the hull of the ship to prevent straining the same.

Other objects of this invention not here specifically enumerated will beevident from the following description of my invention.

My present invention therefore consistsin the novel construction ofdry-dock'hereinafter more particularly descri bed; and also my inventionconsists, furthermore, in such novel arrangements and combinations ofthe several parts of the dry-dock and ,the details of the constructionthereof, all of which will be fully set forth in the accompanyingspecification and finally embodied in the clauses of the 7 claimappended thereto.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure 1 is a plan view of a dry-dock embodying the leadingfeatures of this invention, and Fig. 2 is a longitudinal verticalsection of the dock. Fig. 3 is a vertical crosssection of the dock, saidsection being taken on line 3 3 in Fig. 1, looking in the directionof'arrow X, and said section being made on an enlarged scale. Fig, l isa vertical crosssection of the doclgtaken on line 4 4 in said Fig. 1,said view illustrating more particularly my novel arrangement ofkeels'upports and sliding checks, means for operating the same, and anarrangement of side supports and mechanism for bringing said sidesupports closer to-that is, in holding engagement with-the sideof thevessel or farther away from the same; and Fig; 5 is an end view of saidmechanism for operating the side supports. Fig. 6 is a top view of oneof the keel-supports, and Fig. 7 is an end view of the same. Fig. 8 is ahorizontal section of a pair of gates employed in connection with mynovel construction of dry-dock, and Fig. 9 is a vertical section of thesame. Fig. 10 is a vertical cross-section taken on line l0 10 in Fig. 1.

Similar letters of reference are employed in all of the saidabove-described views.

In said drawings, A indicates my novel construction of a dry-dock, whichcomprises three compartments or chambers A, A ,and A substantially asillustrated in Figs. 1 and 2. The main chamber A, in which the ship isto be docked, and the chamber A are built of masonry, the chamber Acomprising a bottom a and the side walls co" and a said walls a. and aalso forming the side Walls of the chamber A Said walls are made ofsufficient strength to resist a pressure of water equal to their height,the several walls and the bottom of said chambers A and A beingpreferably laid in concreteand clay-paddling. At the front or entranceto the chamber A the based is preferably built up, as at a andmason-Work a is built out therefrom to extend some distance beneath thesurface of the water in front of the outer dock-gate, substantially asare a continuation of the walls of the chamber A, and an inclined bottomor, preferably made of stone. Said bottom a is laid upon a bed ofconcrete and clay-puddling or other suitable material, which ispreferably placed upon a subbottom c of stone, from which eX- tends avertical wall a down into the earth, said wall a forming a part of thechamber A forming a' water-receiving basin into which the water from thedock-chamber A can be admitted, substantially as and for the purposes tobe hereinafter fully set forth. The said chamber A is built directly inthe earth of the shore, forminga suitable caisson, comprising the Wall aabove mentioned, and the sides I) and back wall I), which are made up ofthe usual construction of piling or cribbing filled in with broken stoneto enable the water to more readily soak into the ground. The saidchamber A is surrounded on its sides and back and directly above thesaid sides I) and back wall I) by the stone walls a on said sides I) andthe stone wall a upon the back wall I), said walls being preferably madetapering, substantially as represented in Figs. 1, 2, and 10.

As indicated in dotted outline in Fig. 1 and as more especiallyrepresented in Figs. 1, 2, 3, and 10,1 have provided the walls a, and awith a culvert a, preferably arranged partially below the level aof thechamber A, and being in communication with said chamber through one ormore openings to, which can be opened and closed by means ofsuitably-constructed gates c, as indicated more especially in dottedoutline in said Fig. 3, said gates being raised or lowered by the rods0, when turned by means of the hand-wheels 0 arranged in suitable frameson the upper surfaces of said side walls a and a Said culverts acommunicate by means of suitable outlets (L with an open space a,arranged between the chambers A and A which forms a raceway to permitthe water to flow into drains or culverts a, arranged beneath the upperbottom of the chamber A andinto-the d rain-chamber or caisson A as willbe clearly understood from an inspection of .Fig. 2.

As an extra precaution to more readily remove the water from the chamberA a pipe (Z, connected with a pumping-engine cl in a suitably-arrangedpump-house in the chamber A or any other desirable place, may beemployed, said pumping-engine being capable of forcing the water fromsaid chamber or well A into a discharge-culvert a, substantially asillustrated in Figs. 1, 2, and 3.

As illustrated more particularly in Fig. 1, ladders or stairways e, c,and e may be employed, which can be arranged substantially as indicatedto permit the workmen to get down into the respective chambers forrepairs and cleaning purposes, and the said open space a is preferablycovered by means of a bridge or bridges or to permit the workmen tocross from one chamber into the other. Arranged upon the said built-uppart a of the chamber A are a pair of hinged dockgatesfand f, preferablyof the construction illustrated more especially in Figs. 8 and 9 and thespecial construction of which will be described in detail hereinafter,while upon the cross-wall aibetween the chambers A and A I have arrangeda similar pair of hinged dock-gates f and f substantially as illustratedin Fig. 1. Said gates fand f and f and f have attached thereto at thebottom, so as to be out of harms way, suitable flexible connections f,which pass over pulley-wheels or rollers f and f, secured in framesattached tothe side walls a and a and arranged around the bodies ofcapstans f which when turned will cause said gates to become tightlyclosed. The external gates fandf have also attached thereto suitableflexible connections f passing over rollers or pulley-wheels f and f andaround the bodies of capstans f, which can be operated to open saidgates fand f against the pressure of the body of water on the exteriorsurfaces of said gates. Said gatesfand f and the gates f and f arepreferably constructed of the plates f and f which are connected by theend plates f and f and suitably-arranged stay-bolts f to producestability and at the same time greatly red uce-the weight of each gate.Each gate may be provided at the bottom with suitably-arranged wheels orrollers whereby the gates are more readily turned upon their hinges, andh are suitably-constructed water-inlets in the gates fand f, providedwith valves h, having valve-stems k which are opened and closed by meansof the handwheels 72/ 011 the upper edges of said gates. One or both ofsaid gates may also be pro vided with a ladder f, substantially asillustrated in Fig. 3.

Each gate fand f may have a suitablyconstructed recess, as f, in whichis secured a packing 70, which fits into a recess f in the edge of thegates f and f substantially as illustrated, and i, 7;, and 2' areframe-pieces which are connected with said gates and are provided withpacking-pieces 11 which can be tightly forced into recesses in the gatesby means of screws 1' and, the operating-handles 2' substantially asrepresented in the drawings. Thus it will be evident that after a vesselhas been floated into the chamber A and has been arranged on thekeel-supports Ztherein, the exterior gates fand f closed, and the waterin said chamber A has been permitted to flow into the chamber A the sidewalls a and a may also be employed to make a water-tight fit for thegates at their Mynovel construction of dry-dock A is used in thefollowing manner: Suppose the gates f and f to have been closed and alsothe gate-valves c to have been closed and the gates f and f to be open,whereby the water in the chamber A is on the same level with that on theoutside of the dock to enable the floating of a vessel into said chamberA. The exterior gates f and f are now closed and the gate-valves 0opened. The water in said chamber A immediately passes by its owngravity into the chamber or well A and the keel of the vessel willsettle imposition upon the keel-supports Z. During the passage of thewater from the chamber A into chamber A certain chocks 0, which areslidably arranged on ways or tracks 0 on the supports 0 can be broughtby means of flexible connections 0 against the sides of the hull of thevessel, so as to support the latter upon the keel-supports Z,substantiallyas indicated in Fig. 4. After the water has been removedfrom the chamber A the gates f and f are made water-tight and the gatesf and f can be opened to permit the use of the chamber A by the workmen.As an extra precaution side supports 1* may also be employed, asindicated in said Fig. 4, said supports being pivoted to a carriage s,slidably arranged in ways on the upper surfaces of the walls a and (1 asindicated in Figs. 4 and 5, and operated by means of a suitablegearmechanism 75, substantially as illustrated. Each support T haspivotallyconnected therewith a block 7* to prevent marring or otherdamage to the sides of the vessel. The frame of said carriage 3 maybeprovided with an upright or frame 8 and a grooved wheel .9 over whichcan be passed a flexible connection .5

which is attached to the support '1, to enable the raising and loweringof the latter,'as will be clearly evident, a screw 3 or other meansbeing employed to lock said carriage s in its adjusted position.

The keel-supportsl above mentioned consist, essentially, of the lowerblocks l, provided with nuts I and adjusting-screws 1. therein, saidscrews'having certain angular parts Z ,by means of which they may beturned to raise or lower the main blocks Z, as will be clearlyunderstoodfrom an inspection of Figs. 4' and 7. The blocks 1 have an arrangementof vertical posts Z which extend through holes in the main blocks Z andserve as guides for the proper adjustment of said blocks Z when thescrews Z are turned, certain keys Z,connected with said posts 1, bein gemployed to limit the upward movement of said blocks Z. \Yhen theseveral keel supports have been properly adjusted, wedges Z and Z can beplaced between each pair of blocks Z and Z and driven home to remove thestrain from the screws Z After the ships bottom and sides have beenready for sea the gates f and f are again closed. water is admitted intothe chamber A through the inlets 72 in the gates f and f by opening thevalves 7i. As soon as the chamber A is filled the valves h are againclosed and the gates f and f opened to permit the withdrawal of thevessel from the chamber A,

- which is then ready for occu pancy by another vessel.

The many advantages derived from m invention will be evident from theabove description, and it will be seen that I have devised an operativeand very simple construction of dry-dock.

I am fully aware that many changes may be madein the severalarrangements as well as in the details of the construction of themechanism and parts of the same and in the arrangement and constructionof the cham bers comprising my novel construction of dry-dock. Hence Ido not limit my invention to the exact arrangements and combinations ofthe several mechanism herein set forth nor to the exact details oftheconstruction of the parts thereof. not confine myself to the exactarrangements and constructions of the several chambers A, A and A of thedry-dock.
